A furniture store claims that a specially ordered product will take, on average, μ = 35 days (5 weeks) to arrive. The standard deviation of these waiting times is 5 days. We suspect that the special orders are taking longer than this. To test this suspicion, we track a random sample of 100 special orders and find that the orders took a mean of 36 days to arrive. Can we conclude at the 0.10 level of significance that the mean waiting time on special orders at this furniture store exceeds 35 days? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)

A furniture store claims that a specially ordered product will take, on average, μ = 35 days (5 weeks) to arrive. The standard deviation of these waiting times is 5 days. We suspect that the special orders are taking longer than this. To test this suspicion, we track a random sample of 100 special orders and find that the orders took a mean of 36 days to arrive. Can we conclude at the 0.10 level of significance that the mean waiting time on special orders at this furniture store exceeds 35 days? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)
